To create a strong OC, make her adaptable. In the world of Vampire Knight, things are constantly changing. If she can quickly adjust to new situations, like the discovery of new vampire species or the changing power dynamics at Cross Academy, she'll be more appealing. For Rido, show his leadership skills among vampires. And when he's with the OC, let his protective side come out. Their relationship should be based on mutual respect, and this will make both characters seem stronger in the context of the fanfiction.
One possible plot could be that the OC is a new student at Cross Academy. Rido senses something special about her. He starts to follow her secretly, intrigued by her unique aura. As the story progresses, the OC discovers Rido's true nature but instead of being afraid, she is drawn to him in a strange way. Their relationship develops as they face various challenges together, like the conflicts between vampires and humans at the academy.
In fanfiction, Rido's daughter could be a key figure in changing the power dynamics within the Vampire Knight world. She may form alliances with different vampire clans or even with the human characters. If written as a sympathetic character, she could be a bridge between the vampires and humans, trying to find a way for coexistence. On the other hand, she could also be a more complex and conflicted character, torn between her loyalty to her vampire heritage and her own sense of right and wrong.
Next, think about their powers. In the Vampire Knight universe, purebloods have unique abilities. If your OC has the power of telekinesis, for example, show how they've developed and mastered this power over time. Maybe they struggled with it at first and had to practice in secret. Also, consider how their power affects their relationships. Do other vampires fear or envy them because of it?
To create a believable OC, first consider their backstory. For example, if they're a human, why are they at Cross Academy? Maybe their family has a history with vampires. Then, think about their personality. Are they brave or timid? Curious or cautious? Also, give them some unique traits. If they're an artist, how does that interact with the vampire world? Maybe they draw portraits of the vampires they see, and this causes some vampires to be interested in them.
In Vampire Knight fanfiction, Rido's daughter could play a villainous role. Since Rido was a rather malevolent character, she might follow in his footsteps and cause chaos among the vampires and humans. She could be seeking revenge for her father's death or trying to fulfill his unaccomplished plans of domination.
Another way fanfiction explores their relationship is by looking at their family ties. Yuki's family has a long - standing connection with Rido. Fanfiction can expand on this, like showing how their relationship is affected by the secrets and history of their families. It could be that there are hidden prophecies or agreements that bind them in ways not explored in the original Vampire Knight, and fanfiction can bring these to light and build a new relationship dynamic between Rido and Yuki.
To create a strong OC, consider giving her unique abilities. It could be something like telepathy but with a twist, like she can only read the minds of vampires when they are in a certain emotional state. In terms of appearance, make her stand out. Maybe she has a very rare hair color or eye color that is not common among vampires. And her values should be clear, like she values loyalty above all else, which would play into her relationships with the Volturi Kings.
One interesting fanfiction could be about Rido's past relationship with Yuki's family. Maybe it delves into how his actions were influenced by his feelings for them. For example, it could show that his initial motives were not entirely evil but got twisted over time.
To create a strong OC, think about her motivation. If her main goal is to find her lost family, it gives her a strong drive. In relation to Paul Rovia, she could initially see him as an obstacle to her goal because his group has different priorities. But as they interact more, she realizes they can help each other. Her determination to reach her goal, along with her evolving relationship with Paul Rovia, can make her a very interesting and strong character.
Well, in Vampire Knight Zero x OC fanfiction, the OC has to be well - crafted. It should fit into the dark and mysterious atmosphere of the Vampire Knight world. For example, if the story is set in the Cross Academy, the OC's backstory and abilities should make sense in that context. Maybe the OC has some special vampire - related powers or a unique human trait that draws the attention of the characters from Zero's world.
